I am trying to say the following: "We also drove around California and visited San Diego, Joshua Tree Park and several beaches."
I think it should be:
Kariforunia o doraibu shite sandiego nimo ikimashita. Joshua Tree Park to bi-chi o ikutsuka mimashita.
However, I've been told that "Mimashita" is wrong, because it just means "looked/saw." I tried the verb "kengaku shimashita" but that apparently is also very similar to "looked/saw."
How can I change my sentence to naturally convey the concept of visiting those places?
PS. I have not used hiragana because my skills in hiragana are still at a beginner level and it's just creating too much confusion for me at this stage. The line is only going to be spoken.
